LIQUID 0011mm BE.

This invention relates to liquid containers and method of constructing same, such as are used to carry liquids in considerable quantity, for example, in quantities of 50 6 gallons or more. The object of our invention is to provide a container which shall possess all the advantages inherent in the various types of such containers now known and avoid certain disadvantages inherent in 10 them.

As examples of liquids for which this package is particularly adapted, we will specify nitric and acetlc acids. the package which is adapted to carry' these be used for a large variety of liquids an to its use for any particular llquid.

Nitric acid is a commodity which is widely used as a raw material in the manufacture of chemicals and in other industries. It is extremely corrosive to most metals and to all organicproducts, such as wood or fiber. Under these circumstances, the problem of procuring satisfactory containers has been a difiicult one. v

Hitherto, the only container which it has been possible to use has been the glass carboy. The glass carboy is bulky heavy,

fragile, and of limited capacity. These disthat carboys are only used as shipping containers when no other suitable containers are available.

As a consequence of the fragile nature of the carboy many drastic rules have been promulgated in regard to its use with a view not only of minimizing breakage, and loss of acid, but also of protecting other freight...

Acetic acid has beenshipped in carboys and in containers made of selected white 40 oak of the best quality, sawed from the heart wood of the tree. Before use, these barrels are coated on the inside with molten paraflin. Barrels of this type though widely used are subjectto well known disadvantages. .They

are expensive and even when constructed with the reatest care they permit loss of the contents liy. absorption and leakage. This loss is the occasion of serious'annoyanoe and may become prohibitive in case of long-disshipments unless the barrels are from time to time recoopered while in transit. Moreover, the porous nature of even the best Manifestly we do not limit our invention 5 welded to it. These lugs quality of wood coated with parafiin causes a direct loss of the contents by reason of the absorption of the material by the wood.

.A more serious objection to this type of container is that white oak of the necessary quality is becoming increasingly scarce.

It is found that the requisite qualities of freedom from attack from the aforementioned acids, lightness in ship ing weight and necessary strength of contalner are combmed in aluminum and li ht alloys thereof, whlch are now readily o tainable in sheet form for making the convenient cylinder shaped form herein illustrated, with impervious seams formed-by welding.

. The package which we have invented is mtende to be constructed in sizes to contam gallons and upwards and is superior in several res acts to acid car-boys or barrels hltherto emp oyed for shipments of large quantlties.

Our container is illustrated in the accompanying drawings in which: Figure 1 is a section of form of our improved package.

Figure 2 is a transverse section.

Figure 3 is an enlarged detail.

Figure 4 is a section of alternative form of construction.

Figure 5 is the end view of the alternative form.

Figure 6 is an enlarged detail.

1 is the container of generally cylindrical form made of sheet aluminum by. stamping or spinning, etc; wherein any seams Wlll .be integrally closed by welding so as to produce a unitarycontainer. 2 represents a casing. comprising a cylinder in which the container 1 frlctionally fitsand having external stifiening and rolling hoops 3. To each end of the preferred the container 1 are provided aluminum lugs 5 if desired may be replaced by an aluminum ring welded to each end ofthe container 1. The casin is also provided with corrugations 15 whic serve also as cushions to hold the inner container firmly in place in such manner that blows or shocks delivered to the casing are dissipated before being transmitted to the container.

The casing 2 may preferably be madeof steel which maybe further protected by' lpaint, or other coraluminum bushing 6 as by cap screws 12.

The cap screws may be prevented from turning by soldering to the brass ring after insertion. 8 is an aluminum'end ca'p threaded to the bung 9 which may be of brass or other material. The aluminum end is prevented from turning relative to the bung by any suitable means such as counter-sunk set. screws 11 which also may be prevented from turning by soldering to the bung after in-'- sertion. A gasket 13 made of a iece of thin which fits into the bushin sheet aluminum having a U- aped cross section filled with asbestos completes the joint. Itis known that threaded articles made of aluminum-when screwed together heat .very' materially and tend to seize. In unscrewing such pieces enough force may be uired to strip the threads or otherwise amage them. The ob'ects of abung bushing and bung of this 0 aracter are to provide a closure that will be able to withstand the wear and tear on the threads incident to the repeated use of a container of this sort and at the same time prevent the contents from coming in contact with any metal other than aluminum.

16 is a removable aluminum spout seating on the bushing gasket 13 and provided with a fastening nut of brass or other metal threads. The upper end of the spout is t readed for connection to usual drum discharging appara tus. The object of this s out is to facilitate emptying the drum wit ut the contents coming 1n contact with the-upper part of the bung bushing or the casing.

In assembling, the container 1 is completely fabricated including welding thereto the aluminum art of the bung bushin 6 and .the lugs 5 or an aluminum ring if it is desired to use it in place of the lugs). In making the two concentric welds 10 which secure the bung bushing 6, the aluminum sheet surrounding the bung bushing becomes annealed from the heat-of the welding. This permits the bung bushing 6 being driven into the container 50 that its u per edge is flush with the surface thereof wlthout cracking or. otherwise injuring the container.

With the bushing/B in this position the container is pushed into the casing 2 until the lugs 5 are flush with the ends of the casing, the bushin .-in the container and the hole in the casing ing concentric. The end rings mega 4 are then fastened in place as by putting r vets through the caslng, lugs and en rings. The ung bushing 6 is then pulled out to its original position by means of a hook and the brass part 7 placed'into sition secured by the fastenings 12. fie lugs 5 being fastened by means of the end r ngs 4 preventsv both longitudinal and rotational movement. The ]package can now be filled and the b app 'ed and sealed in a known manner. he casing when ready to receive the container is galvanized and protectively 'coated inside. and out and the end rings are similarly protected so that there 1311017111118 to rust or corrode.

The conta ner as described above is capable of successfully withstanding the'most severe conditions a liquid container may be called upon to meet. Where conditions are less severe such as when the container is used for other'than acid liquors, an alternative form as shown in F1 4, 5, and 6 may be entirely suitable. if: an example of a liquid which may be suitably ship (1 in this alternative form we specify formaid ehyde solutions.

29 is a container of the same shape' and construction as 1.' 30 is a casing corres 0nding to 2 in Fig. 1. Owing to the thic ess of the material of which the container 1 may be made the ends of the casing need not be closed b the lugs 5 e provided. The ends of Fig. 4 being shown open and the container secured in position by means of angle iron rings 18 o y. Rolled in rolling hoops 18 may be provided in place of I beam rolling hoops 3. Both the container and easing are provided with holes in the side which will register in close contact when the container is pushed into the casing and abuts one of the end rin 19. These holes are closed by a bung bus 'ng and the bung shown in detail in Fi 6, wherein 20 represents the bung bushing, 22 a gasket which fits in a larger hole in the casing 30 so as to rest on the container 29 and 23 represents the fastenings which fasten the bushing to' the contamer. 25 represents the bun with square socket hole screwed in the bushing 20 a ainst the gasket 26. The thickness of metal m the bung bushing '20 may preferably be great enough to permit having one or more new threads being tapped into the bushing 20 as at 21 when the original thread becomes worn. It is understood that when larger threads are installed a larger bung will be required. 24 represents holes drilled through the bushing 20 in line with the inside wall of the container 29 to permit and complete emptyin of the container. 2 represents an apron astened to the bung bushing 20 by means Of'the same fastening 23 as secured the same bushings to the con tainer which extends over the outer shell 30 circles 14 in Fig. 1 nor need in order to prevent the outer shell from riding over the bung and bushing.

In assembling, the container 29 is pushed into the casing 30 until it strikes one of the end rings 19, with the holes in the casing and container concentric; Then the bushing and gasket are applied (the bung being removed) and the fastenings 23 inserted through the fastening holes in the container -and the fastening holes in the bushing and flange, and externally fastened as by nuts. When this is completed the other end ring 19 is applied and fastened, so that the end rings hold the container against longitudinal movement and the bushing flange and apron prevent rotation. The package can now be filled and the bung applied and sealed in a known manner.

The casing when ready to receive the container is galvanized or otherwise protec tively coated inside and out, the end ring last to be applied being also similarly protected so that there is nothing to rust or corrode. n
